Question

我试图通过使用python检查目录中图像的宽度和高度。该目录由两个文件夹组成，每个文件夹都有图片想要检查宽度和高度，如果它们不匹配则调整它们的大小。这是我的代码：

def Resize(imageFolder, factor_1, factor_2):


    for path, dirs, files in os.walk(imageFolder):
       for fileName in files:

         image = Image.open(fileName)
         image_size = image.size
         width = image_size[0]
         height = image_size[1]
         if ((width and height) == 224):
            print("the width and height are equals")

            continue
         print("the width and height are not equals, so we should resize it")    
        resize_pic(path, fileName, factor_1, factor_2)

当我运行代码时给出错误，我认为循环不对。任何帮助？

 Traceback (most recent call last):

 File "resize.py", line 62, in <module>
 Resize(imageFolder, resizeFactor , resizeFactor_h)

 File "resize.py", line 46, in Resize
   image = Image.open(fileName)

 File "/usr/lib/python2.7/dist-packages/PIL/Image.py", line 2028, in open

 raise IOError("cannot identify image file")

 IOError: cannot identify image file

Answer 1

for (pth, dirs, files) in os.walk(imageFolder):
    for fileName in files:
        image = Image.open(fileName)
        with Image.open(os.path.join(pth, fileName)) as image:
            image_size = image.size

您需要提供文件的绝对路径，如上所述。

同时检查图像文件格式

检查图像的宽度和高度
